Its great to see a pico-8 entry!
The controls are smooth, and the game plays as expected without any bugs!
The art is very simple yet charming, which is hard to pull off in the Pico limitations.
I thought it was weird that the acorn had no top, but it made sense at the end.
I didn't really feel like I was in a pocket at all, but there was a pocket in the level select room, and acorns do fit in pockets. The gameplay is not the most creative, but it does work well and that is important!
The music sounded great at first but by the end of the 7 minutes I played, I was wishing that there was a chord change or more to the baseline, or something.. it was too repetitive after a few minutes. A new song for each level would have been fantastic.
The sound design is good! I didn't feel like any sounds were missing or out of place.
I Couldn't find the pico-8 cart PNG in the zip, not that this is necessary, but I would add this to my handheld device!
Awesome to see so many people coming together to make a single jam game!
